# OpenFlare
A lightweight, self-hosted OpenResty control plane for reverse proxy management, configuration rollout, node sync, TLS assets, and practical observability.

OpenFlare `1.0.0` is the current stable baseline. Phase six is complete and fully shipped; the repository documentation now focuses on the living system rather than historical implementation notes.
## Why It Exists
OpenFlare is built for a simple but recurring operational need:
* manage domain-to-origin reverse proxy rules from one control plane
* publish immutable OpenResty configuration versions
* let Agents pull, validate, reload, and roll back safely
* manage certificates, domains, node credentials, and version state
* expose practical dashboards for traffic, node health, and rollout status
It is not trying to be a CDN SaaS platform, a multi-tenant control plane, or a general-purpose logging system.
## Core Capabilities
* Versioned configuration with preview, publish, activate, and rollback
* Node onboarding with `discovery_token` or per-node `agent_token`
* Automated Agent apply flow with `openresty -t`, reload, and rollback
* Managed OpenResty templates, performance settings, and cache settings
* TLS certificate and domain management with exact and wildcard matching
* Request analytics, node snapshots, and health event reporting
* Controlled Server and Agent upgrade flows
* A production frontend built with Next.js App Router, React 19, and Tailwind CSS 4
## Architecture
```text
OpenFlare Server (Gin + GORM + SQLite/PostgreSQL + Web UI)
|
| HTTP API / Config Pull
v
OpenFlare Agent (register / heartbeat / sync / apply / update)
|
v
Local OpenResty or Docker OpenResty
|
v
Origin
```
Responsibilities:
* `openflare_server`: admin UI, management APIs, Agent APIs, rendering, rollout, and state storage
* `openflare_agent`: node registration, heartbeat, sync, local apply, validation, reload, rollback, and self-update
* `openflare_server/web`: the production admin frontend, exported statically and served by the Go server

## Quick Start
### 1. Start the Server
```yaml
services:
postgres:
image: postgres:17-alpine
restart: unless-stopped
environment:
POSTGRES_DB: openflare
POSTGRES_USER: openflare
POSTGRES_PASSWORD: replace-with-strong-password
volumes:
- postgres-data:/var/lib/postgresql/data
healthcheck:
test: ["CMD-SHELL", "pg_isready -U openflare -d openflare"]
interval: 10s
timeout: 5s
retries: 5
openflare:
image: ghcr.io/rain-kl/openflare:latest
restart: unless-stopped
depends_on:
postgres:
condition: service_healthy
ports:
- "3000:3000"
environment:
SESSION_SECRET: replace-with-random-string
SQLITE_PATH: /data/openflare.db
DSN: postgres://openflare:replace-with-strong-password@postgres:5432/openflare?sslmode=disable
GIN_MODE: release
LOG_LEVEL: info
PORT: "3000"
volumes:
- openflare-data:/data
volumes:
postgres-data:
openflare-data:
```
```bash
docker compose up -d
```
Open `http://localhost:3000`
Default credentials:
* Username: `root`
* Password: `123456`
### 2. Install an Agent
First-time registration with `discovery_token`:
```bash
curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
--server-url http://your-server:3000 \
--discovery-token YOUR_DISCOVERY_TOKEN
```
Registration with a per-node `agent_token`:
```bash
curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
--server-url http://your-server:3000 \
--agent-token YOUR_AGENT_TOKEN
```
The installer writes to `/opt/openflare-agent` by default, creates `openflare-agent.service`, and can be re-run for reinstall or upgrade.
### 3. Publish Your First Config
1. Sign in and create a reverse proxy rule
2. Review the preview or diff
3. Activate the new version
4. Wait for Agents to pick it up on the next heartbeat
Version numbers follow `YYYYMMDD-NNN`. Versions are immutable; rollback is implemented by reactivating an older version.
## Repository Layout
* `openflare_server`: monolithic control plane built with Gin, GORM, and SQLite/PostgreSQL
* `openflare_server/web`: admin frontend built with Next.js 15 App Router
* `openflare_agent`: Go Agent
* `scripts`: install and helper scripts
* `docs`: design, guidelines, deployment, and configuration docs
## Local Development
### Server
```bash
cd openflare_server
export SESSION_SECRET='replace-with-random-string'
export SQLITE_PATH='./openflare.db'
# Optional: switch to PostgreSQL by setting either DSN or SQL_DSN.
# If the PostgreSQL database is empty and ./openflare.db exists,
# OpenFlare migrates SQLite data automatically at startup.
# export DSN='postgres://openflare:secret@127.0.0.1:5432/openflare?sslmode=disable'
go run .
```
### Frontend
```bash
cd openflare_server/web
corepack enable
pnpm install
pnpm build
```
### Agent
```bash
cd openflare_agent
go run ./cmd/agent -config /path/to/agent.json
```
### Useful Checks
```bash
cd openflare_server
GOCACHE=/tmp/openflare-go-cache go test ./...
```
```bash
cd openflare_agent
GOCACHE=/tmp/openflare-go-cache go test ./...
```
## Admin Surface
The admin UI currently covers:
* reverse proxy rules
* config versions
* node management
* apply logs
* TLS certificates
* domain management
* user management
* settings
* version upgrades
Swagger UI is available at `/swagger/index.html` after login.
